Gilbert Chagoury is not a name that dominates newspaper front pages, but his fingerprints are on some of the biggest infrastructure projects in Africa, the corridors of power in multiple countries, and the walls of the Louvre. The Nigerian-Lebanese billionaire has spent over five decades building a business empire that spans construction, manufacturing, hospitality, and real estate across West Africa, while quietly cultivating political relationships that have influenced governments and secured contracts worth billions. His story reveal ambition, philanthropic generosity, and controversies that have followed him from Geneva to Washington D.C.
Biography
Gilbert Ramez Chagoury was born on January 8, 1946, in Lagos, Nigeria, to Lebanese immigrant parents from the town of Miziara in northern Lebanon. He grew up straddling two worlds, and that bicultural upbringing would later prove one of his greatest business assets.
He is the eldest of eight children. His parents, Ramez and Alice Chagoury, migrated from Lebanon to Nigeria in the 1940s and built a life there while keeping their Lebanese roots firmly intact. The family belongs to the Maronite Catholic tradition, and Gilbert has remained a devout Catholic throughout his life, earning some of the Vatican’s highest honours along the way.
For his education, Gilbert was sent back to Lebanon, a common path for children of the Lebanese diaspora in West Africa, where he studied at the Collège des Frères Chrétiens (College of the Christian Brothers). He returned to Nigeria as a teenager, just in time to witness the country’s transition into independence, and got straight to work.
Career
Chagoury’s career started at the bottom, quite literally. He began selling shoes, then moved into the automobile industry, rising quickly to become the youngest national sales director at a major car company. By 25, he had learned enough about business and emerging markets to co-found the Chagoury Group in 1971 alongside his brother Ronald Chagoury. Ronald officially joined the enterprise in 1974, and what began as a construction-focused venture soon grew into something far larger.
By the late 1970s, the brothers had established C&C Construction Company, which eventually gave rise to major subsidiaries including Hitech Construction and ITB Nigeria Limited. Hitech would go on to build roads, bridges, railways, and marine works across the country, while ITB delivered landmarks like the National Assembly Complex in Abuja and the InterContinental Hotel on Victoria Island.
Today, the Chagoury Group is one of West Africa’s largest diversified conglomerates. It spans construction, real estate, manufacturing (four flour mills, glass production, water purification, aluminium, and furniture), hospitality, telecommunications, insurance, and international financing. In hospitality alone, the Group owns Eko Hotels & Suites, Nigeria’s largest hotel with 825 rooms, and Hotel Presidential in Port Harcourt.
Three mega-projects currently define the Group’s ambition. First, Eko Atlantic City, a $6 billion-plus development reclaiming 10 million square metres of land from the Atlantic Ocean off Victoria Island, Lagos. Granted to the Chagoury Group in 2007, the project is designed to house 250,000 residents and 150,000 daily commuters, with multiple residential towers already operational and the US government constructing its largest consulate worldwide on a 12.2-acre site within the development. Second, the Lagos-Calabar Coastal Highway, a 700-kilometre six-lane dual carriageway awarded to Hitech Construction in 2024 at an estimated cost of $11 to $13 billion. By December 2025, the first completed section had already opened to traffic. Third, the renovation of Lagos’s Tin Can and Apapa ports, worth up to $1 billion, plus a new $1 billion Snake Island container terminal signed in March 2026 through a 45-year concession with Swiss shipping giant MSC Group.
Together, these projects represent over $13 billion in federal contracts flowing to Chagoury entities under the current administration.
Political Influence
Few private citizens in Africa have wielded political influence as quietly or as effectively as Chagoury. His relationships with heads of state span decades and cross borders, and understanding his business success is almost impossible without understanding his political connections.
Within Nigeria, his most controversial alliance was with military dictator General Sani Abacha in the 1990s, serving as Abacha’s personal economic adviser while securing major government contracts. That relationship later attracted serious legal scrutiny when a Geneva court convicted him in 2000 of money laundering linked to Abacha-looted funds, imposing a fine of 1 million Swiss francs and ordering the return of $66 million to Nigeria. He also reportedly secured immunity from Nigerian prosecution by returning an estimated $300 million in funds held in Swiss accounts.
His influence inside Nigeria didn’t end there. Under President Bola Tinubu, who granted the Eko Atlantic land concession during his Lagos governorship (1999 to 2007), Chagoury has re-emerged as a central figure. He backed Tinubu’s 2023 presidential campaign, and since Tinubu took office, every major infrastructure contract has gone to Chagoury Group entities without public competitive bidding. Leaked documents from the ICIJ and OCCRP in August 2024 revealed that Tinubu’s son Seyi Tinubu held shares in a British Virgin Islands company alongside Ronald Chagoury Jr., Gilbert’s nephew, deepening questions about the two families’ commercial ties. On January 8, 2026, Tinubu conferred Nigeria’s second-highest national honour, the Grand Commander of the Order of the Niger (GCON), on Chagoury. The award wasn’t publicly announced and only became known when Femi Otedola posted the certificate on social media.
Outside Nigeria, his political reach is equally impressive. Since 1995, he has served as Ambassador and Permanent Delegate of Saint Lucia to UNESCO in Paris, funding the entire mission at his own expense. He later became Saint Lucia’s Ambassador to the Holy See in 2005, and also represents the country at the UN Office in Geneva. He served as economic adviser to President Mathieu Kérékou of Benin from 1996, a role he continued under President Boni Yayi.
He has received national honours from six countries, including France, Lebanon, Chad, Benin, Rwanda, and Saint Lucia. His Vatican honours are among the most distinguished, culminating in the Knight Commander with Star in the Order of Pope Pius IX, conferred by Pope Francis in 2016. In the United States, his influence ran into legal complications. In 2019, he entered a deferred prosecution agreement with the US Department of Justice, admitting responsibility for funnelling approximately $180,000 through straw donors to four US political candidates and paying a $1.8 million fine. His donations to the Clinton Foundation and a 2009 email requesting State Department access on his behalf also drew intense media scrutiny during the 2016 presidential campaign.
Personal Life
Chagoury married Rose-Marie Chamchoum in 1969, having met her during a visit to Lebanon in 1967. She was born in the Republic of Niger to a prominent Lebanese family from the same village of Miziara. Together they have four children: Ramez (deceased, memorialised through a faculty naming at Notre Dame University-Louaize in 2016), Gilbert-Antoine, Christopher (who holds an LL.M. from NYU School of Law and now chairs Eko Hotels), and Anne-Marie. The couple also have five grandchildren.
He maintains residences in Paris, Beverly Hills, and Victoria Island, Lagos. Despite his enormous public footprint, Chagoury is intensely private. The fact that a major national honour had to be revealed by someone else on social media says a great deal about how he prefers to operate.
His philanthropic record is substantial. He and Rose-Marie founded the $10 million Gilbert and Rose-Marie Chagoury School of Medicine at the Lebanese American University, established in partnership with Harvard Medical International and opened in 2009. He separately donated $3.5 million for the Alice Ramez Chagoury School of Nursing, also at LAU. The Louvre Museum in Paris dedicated a permanent gallery in their name in September 2000 after the couple donated rare 16th-century tapestries and Louis XVI-era Sèvres vases. His ties to St. Jude Children’s Research Hospital go back to 1980, when he first met founder Danny Thomas.
Net Worth
Gilbert Chagoury’s net worth is widely cited at $4.2 billion, though some Nigerian sources place the figure as high as $4.5 billion. It’s worth noting that he does not appear on the official Forbes Africa or World Billionaires lists for 2024 or 2025, making independent verification difficult given the entirely private nature of the Chagoury Group.
What’s not in dispute is the scale of the assets behind those estimates. Eko Atlantic alone represents a $6 billion-plus development. Eko Hotels is valued at over $200 million. Active construction contracts exceed $13 billion. The Group previously controlled South Atlantic Petroleum, a portion of which was sold to China’s CNOOC for around $2.7 billion circa 2007, a transaction that likely contributed to earlier wealth estimates. At whatever the precise figure, Chagoury sits comfortably among Africa’s wealthiest individuals, with a business empire that continues to grow.
